Oh bro showing me how to fix one of those connectors by taking it apart properly. ..... PRICELESS. Bless you dude!

[@tonyarro7986]

I had initially thought about changing Clips, however now that I think about it, good idea. I like your video on the clip change. Quick and clean. Way to go.

[@steverojas27]

this video saved me alot of time and money.. the ac fan was blowing the opposite direction>> the wires where crossed the blue and black wire" causing the fan to rotate the wrong way it was blowing out air instead of sucking in and cooling the engine.. after i easily switched the wires the ac started working AGAIN.. my issue was the cars ac would only work while driving" at a stop the car would stop cooling... I tore a small piece of paper and through it towards the inside of the cooling fan and it sucked it right in.. the paper should have been thrown out, as the cooling fan sucks air from the outside into the condenser..

[@teravolt6113]

In my case, no overheating at all, simply really wimpy AC and a loud AC compressor in hot and sunny summer days only... but the refrigerant charge was perfect and both the condenser and radiator were clean. Caught it in time and fitted a new one before things got messy. Got to turn the blades by hand on the old one and it felt grainy, like shot bearings... didn't make any obvious noise at all while running though. New one is definitely louder, like 5 times the airflow, btw...

It helps to 'match mark' the wires in relation to the connector housing before disassembly either by etching the housing ('B' for blue, 'G' for green, etc....) or by a paint-pin color matching on the housing.

[@tolorated5757]

appreciate the video, I was able to reverse the posts in the connector and now my fan is blowing in the right direction.

THANK YOU, beautiful instsruction, IF, I could get this far, I have a 2006 Crown Vic and I can't get the male & remale plugs apart going into the fan relay

[@Nthefastlane]

Yes Kurt, most definitely..the more (cfm) the better.

[@luckienuckie]

thanks very nice video! can cleaning the fan dc motor help fix the fan? or is fan replacement immediately needed in cases like the fan does not spin when directly connected to 12 volts?

[@sayian2k]

Thanks for the upload having this problem and looking forward to fixing it.

[@TheGeno2001h]

Man you safe me time and money great video and thanks for your time brother

[@rey8415]

is there supposed to be continuity between both connections at the fan itself? or does that mean my fan is bad and that's why my fan fuses keep blowing? because I've tested my relays and they're working fine

[@MMD-z6z]

Thanks for that great info

[@isaacthibodaux667]

If u accidentally break the clip while still on the car can it still come apart?

[@zar5989]

Question! Do you think that the noise coming from the cooling fans is a problem that should be improved in modern cars??

[@Nthefastlane]

+Zar Good question, I think inorder to make the fan quieter, they would have to work on certain pitch angles of the blades, also maybe some kind of insulated noise barrier, but then that might hold in heat. There is a lot of different angles to be looked at.

[@zar5989]

Nthefastlane yes, but do you think it's something that it's worth to work on it or the percentage of the noise is much inferior to the one produced by the engine?

[@Nthefastlane]

+Zar My opinion is, it doesn't matter or bother me. The noise produced by the fan, is equal or just a little more then the engine at idle. If it were to be quieter, I'd worry it wasn't producing enough cfm to cool things down.

[@zar5989]

Nthefastlane to be honest, I'll start the next week a PhD right on this topic: the control of the flow and the noise in automotive low-speed cooling fans and that's why I was asking this question 😂 actually it will be applicable to a larger range of fans, like the helicopter blades or the HVAC systems. I think it's important to silence as much as possible this kind of noise, even if I discovered right yesterday that KZbin is full of 10 hours videos with people listening to a rotating fan noise just to sleep better 😂😂and that's paradoxical 😂

[@WavyVaporizers]

I changed the sensor switch on top of the thermostat and the 2 sensors below the distributor and my cooling fan doesnt come on when u turn on the ac and it's supposed to but never does. I checked my relays and fuses and they're fine. I thought maybe my fan needs to be replaced but I ran alligator clips from the cooling fan directly to the battery and the cooling fan came on with no problem. So my question is why isnt my cooling fan turning on when I turn on the ac???? The fan on the driver side comes on without any problems.

[@cooldude2245]

Is it possible that you don't get enough power to the fans? Or the fans don't spin fast enough to move air and stop overheating?

[@kennethpalmer2160]

Real good information thank you

[@lynettebell6104]

my fan stopped and now my car is running hot test the fan and the clutch thanks in advance for any information

[@kelsivy1]

What is the wiring harness connect to?

[@louiseevegan3154]

hi nthefastlane will it blow my other fuses if i keep the wire on my fan and battery to keep the fan on while i drive

[@marked4death076]

So hey i got here because my fan wasnt turning untill i reached down were it was plugged into it and grabbed the wiring...then it works? Could it just be its not connected all the way or does the whole wire need to be replaced?

[@Nthefastlane]

It sounds like the plug may have a loose connection. I would unplug it and bend the pin inside a little bit so it makes better contact.

[@Nthefastlane]

Also check to make sure that the pin didn't come out of the plug, I demonstrate this when I'm swapping the pins out on the plug, if the wire pulls back too much it will disconnect inside the plug.

[@marked4death076]

@@Nthefastlane thank you man ill take another look at it....i unplugged it today and cleaned both connections but i could only see the part that plugs in and it looked good. The fan part i cleaned out but really cant get a look inside cuz i didnt take fan out. It did same thing still....so i ordered new fan today

[@marked4death076]

@@Nthefastlane yep it was the fan. New one started working right away thank God haha

[@albertcabrerajr9381]

Is the radiator fan supposed to push air towards the radiator? Or pull air from the radiator? becoz mine is pulling air from radiator but is not effective and radiator is heating up... only the condenser fan is pushing air towards the radiator...

[@Nthefastlane]

If the radiator fan is on the inside of the engine bay it's supposed to pull air. If the radiator fan is in front of the radiator towards the front bumper then it's supposed to push air.

[@albertcabrerajr9381]

@@Nthefastlane thanks very much... i've fixed the problem... i noticed the condenser fan spinning the wrong direction blowing air towards the radiator... just reversed the connecting wires and that temp reading got fixed... thanks much

[@nismo2ful]

sr my jeep 99 grand cherokee overheat when is at idle and ac on and fan works but i think is to slow is nrand new i just put it on last year what else besides that could be the problem thanx and good vid

[@travelinthru9519]

that's all fine and dandy but how do you test your fan to make sure it's running up to speed just cuz it's spins doesn't mean it's running up to par

[@superjohn8091]

Nthefastlane when I turned the heater on both fans spin but it doesn’t turn on when the car is hot and it’s making the vehicle overheat I checked the relays I change the temperature sensor and radiator and thermostat

[@ebeegeebeefofeebee3181]

Very well old man.

[@pradeepmenon7035]

hi in my car,the coolant container show always shows significant decrease in one week even if i refilled it to maximum...i checked if there is any leak on the bottom of the vehicle,but i could not find any leakage...could u please tell me wat will be the possible reason for this?

[@cabjroman10]

does this fan only have one speed, considering it only has 2 pins?

[@ryuhadooken5609]

one of my fans doesnt work and ive changed it not long ago what could be the cause of it

[@Nthefastlane]

Check the fan relay or fuse. Sometimes smacking the fan relay while the vehicle is running will turn the fan on, if that happens the relay is bad. The fuse box should be located in the engine bay. If that doesn't check out, you might have a short in the wire somewhere.

[@munwarh4576]

Nice tutorial i love it.

[@seven794]

thanks for this vid bro

[@MrLuhbat49]

My cooling fan only works when I wiggle the wire but sometimes it a come on when I'm driving and sometimes it won't come on what. Do you suggest I have an 1998 mercury grand marquis

[@thugangel141]

my fans when i plug to battery it seems like its shorting out but doesnt spin its bad right ?

[@Nthefastlane]

Yes, 100% bad. Unless the battery you're testing with is dead. Even say the battery had 8v, it should still spin a little.

[@thugangel141]

Right thankx man 👍

[@zharrold1able]

I put new fan in backwards because I hooked wires up backwards. All is well.

[@jidecoker1723]

My ford escape cooling fan did work. What the problem

[@betzabegonzalez8279]

my fan only work if i make it do it with my hand,thats a bad fan right? i mean i need all the assembly right" is nissan versa

[@Nthefastlane]

Yes, the brushes in the fan that make current through the motor sleeve are burnt out. Fan needs replaced.

[@MarkosHaas]

New fan came with male end and should be female. Also, came with no ground wire. What can I do here?

[@rajamahamud4036]

rite

[@nickmaglio1884]

My fan stoped working . Fan plug is burnt out. How do I go about fixing it.

[@mohammedel-gazzar9145]

my fan does not start when the temp exceeds 90, but when I rotate it with my hand it starts. what do you suggest? thank you in advance.

[@spacegrace6309]

Mohammed El-Gazzar same here

[@TeamWhos]

is the fan still installed? it might be rubbing on the radiator somewhere preventing it from turning on its own

[@mohammedel-gazzar9145]

Tyler Borbon no I disassembled it I found a molten brush

[@Nthefastlane]

The brushes in the fan are burnt out. Time to replace the fan. This should help. www.nthefastlane.com/AC-System/AC-condenser-fan-replacement-honda-civic-92-00
